MOPEKA PRODUCTS LLC | Pro200B Antenna Report | 1 / 3 MOPEKA PRODUCTS LLC Mopeka Pro200B Antenna Report Bent PCB monopole | Reference design and simulation Permanent attachment. The antenna is etched directly into the PCB copper and permanently attached to the device. It is not a separately replaceable component, and the product has no detachable RF antenna connector. This construction uses the permanently attached antenna provision of 47 CFR 15.203. Nordic nRF52 DK reference PCA10040 v1.2.4 / PCB 400150 Rotated and mirrored for comparison Unshorted printed bent monopole. Native layout: 12 December 2017; schematic/layout PDF pp. 2, 8- 9. nRF52832 development kit. Trace width: 1.270 mm. Main route centerline: 22.736 mm. Board: approximately 101.60 x 63.50 mm. Four-layer CAD stack; approximately 1.6 mm. Nordic's hardware files provide the antenna geometry reference. Its published DK Q&A describes gain around 0 dBi. Mopeka results are calculated from the separate PRO200B model. Design comparison. PRO200B and PCA10040 use an unshorted bent printed monopole. Their trace widths, routes, ground planes and PCB stacks differ. PCA10040 includes an RF test connector and a 1.2 pF antenna shunt; PRO200B uses its own feed arrangement. Mopeka PRO200B antenna Bottom copper / rev C / flat open end M2006211C / M2006212C Trace width: 0.800 mm. Copper envelope: approx. 12.27 x 11.30 mm. Main centerline: 24.144 mm. Open-end pad: 0.800 mm square. No grounded shorting arm. Board: 36.00 x 40.50 mm. Four layers; FR-4/prepreg, approximately 0.8 mm CAD stack. Ground-envelope inset; inner voids omitted. Blue: antenna projection. Construction and feed. Integral copper for BLE channel centers 2402-2480 MHz. The nRF52810-QCAA ANT pin 19 feeds C15 0.8 pF shunt and L3 3.9 nH series; C36 is not fitted. The radiator lies over a copper-recessed region on all layers. The assembly has two top-side CR2032 cells and holders. Dimensions follow native layout and released rev C copper. The 24.144 mm route includes bends and joining segments; narrower feed routing and the terminal-pad extension are excluded. The open-end pad is square. Simulation result. Highest sampled total gain is 2.156 dBi at 2480 MHz for the PCB, battery, enclosure, foam and potting model. Results cover 2402, 2440 and 2480 MHz on a 3-degree spherical angular grid. The model configuration and numerical results follow.
